scsi: mpi3mr: Fix pending I/O counter

Browse Source 
Commit 199510e33d ("scsi: mpi3mr: Update consumer index of reply
queues after every 100 replies") introduced a regression with the
per-reply queue pending I/O counter which was erroneously decremented,
leading to the counter going negative.

Drop the incorrect atomic decrement for the pending I/O counter.
